Description

Technical Field

[0001] The present application relates to the technical field of steam turbine valve casings, and in particular to a steam turbine valve casing transport device. Background Art

[0002] The turbine valve casing is one of the important components of the turbine. It is usually located on the main steam pipe in front of the regulating steam valve. Its main function is to control the steam flow and pressure entering the turbine. The valve stem will be subjected to a large impact force during operation. The valve stem should be made of heat-resistant steel with good impact toughness, and its cross-sectional size should be selected to ensure that it can withstand this impact force. Sudden changes in the cross-sectional size of the valve stem should be avoided, and stress concentration should be avoided as much as possible.

[0003] After checking the announcement number: CN217044557U, a shell mold transfer vehicle is disclosed.

";

[0004] With respect to the above-mentioned related technologies, the inventors believe that the existing steam turbine valve casing transfer device is not convenient for the installation and disassembly of the supporting structure. Since the number of steam turbine valve casings that need to be transferred each time is different, if the supporting structure is not convenient for installation and disassembly, only a structure with a fixed transfer number can be used for transfer, which adds unnecessary weight and is inconvenient to repair when part of it is damaged. In addition, the existing steam turbine valve casing transfer device cannot be adjusted according to the size of the steam turbine valve casing. Since there are multiple types of steam turbine valve casings with different sizes, if only steam turbine valve casings of a single size can be transferred, there will be great limitations. Therefore, a steam turbine valve casing transfer device is needed to solve the above problems. Utility Model Content
